Police are trying to work out what caused a car and its two passengers to fall from a Newmarket carpark building last night.
A 30-year-old woman remains in critical condition at Auckland Hospital along with a 39-year-old man who is serious but stable.
Police say the car is likely to have plunged from the carpark building onto York Rd around 8:40pm.
The vehicle landed on its roof, on top of another vehicle parked in the street. Nobody was in the parked car.
The serious crash unit is investigating.
